Hi I have recently installed xen on fedora core 6 on an AMD Athlon 1700. It has 512 meg of memory. When I boot the xen kernel the system crashes and reboots fairly soon in the startup. I have installed xen on fedora core 6 on a Pentium 4 and experience no such problem. Should I report this as a bug? ian xen-3.0.3-6.fc6 fc6 #1 SMP Sat Feb 10 15:03:33 EST 2007 i686 athlon i386 GNU/Linux _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

There should be no problem running Xen on AMD hardware, and my suspiction is that the difference between the machines are more in which drivers you need to get the kernel booted rather than the processor architecture... [The number of times we''ve had customers saying things like "it works on my Intel machine but not the AMD machine" and it turns out to be some other hardware difference is HUGE compared to number of cases where software ACTUALLY is bevhaving different between AMD and Intel.] -- Mats> > ian > > xen-3.0.3-6.fc6 > fc6 #1 SMP Sat Feb 10 15:03:33 EST 2007 i686 athlon i386 GNU/Linux > > _______________________________________________ > Xen-users mailing list > Xen-users@lists.xensource.com > http://lists.xensource.com/xen-users > > >_______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
Thanks for your reply. I tried this, and it now hangs during boot, whereas before it rebooted itself. Which drivers might I be missing? Perhaps there is a missing dependency...

It''s a useful thing for debugging startup-problems, as it gives you a chance to read the console output.> > Which drivers might I be missing?

You may want to do lsmod on your system running Linux without Xen and see what''s listed there, and compare that to what you find in /lib/modules/linux-2.x.y.z-xen/... Pay particular attention to things like file-system modules, SATA/IDE/SCSI modules - sound-card drivers or such are unlikely to prevent the system from booting. If you''re not able to make sense of the above, the output to the console would be helpful. The best way to capture the information is to connect a serial-port of the target-machine to a another machine, and add: com1=115200,8n1 console=com1 sync_console to the xen.gz line in your grub.conf file. Then use a serial capture application (minicomm, teraterm, HyperTerminal or whatever you have available) to log the output to a file. Copy the last dozen or so lines of the output to a reply to this mail. The less pleasant method of achieving the same thing is to type it in by hand (and trying to not type it in wrong, as that may mislead the helper...). -- Mats> > Petersson, Mats wrote: > > You may want to add "noreboot" to the "kernel=[...]xen.gz" > line in your > > grub.conf file. > > > > There should be no problem running Xen on AMD hardware, and my > > suspiction is that the difference between the machines are > more in which > > drivers you need to get the kernel booted rather than the processor > > architecture... > > > > [The number of times we''ve had customers saying things like > "it works on > > my Intel machine but not the AMD machine" and it turns out > to be some > > other hardware difference is HUGE compared to number of cases where > > software ACTUALLY is bevhaving different between AMD and Intel.] > > > > -- > > Mats > > > >_______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Would you believe I took a photograph of it with my digital camera? :) It doesn''t look very revealing though. The last thing it says is "xen trace buffers: disabled" then silence. ian Petersson, Mats wrote:> > > >> -----Original Message----- >> From: Ian Jones [mailto:ian.jones9901@yahoo.co.uk] >> Sent: 27 February 2007 13:33 >> To: Petersson, Mats >> Cc: xen-users@lists.xensource.com >> Subject: Re: [Xen-users] xen kernel crashes athlon? >> >> Thanks for your reply.

The last thing it says is "xen > trace buffers: disabled" then silence.Hmm - that''s very early during boot. I''m not sure exactly what happens after that, but I''m very surprised it hangs at that point... Just a thought, almost the next thing that happens is that Xen jumps to the Linux kernel - any chance that you''ve got a broken vmlinuz file? Try copying the one from your intel machine, perhaps? -- Mats> > ian > > Petersson, Mats wrote: > > > > > > > >> -----Original Message----- > >> From: Ian Jones [mailto:ian.jones9901@yahoo.co.uk] > >> Sent: 27 February 2007 13:33 > >> To: Petersson, Mats > >> Cc: xen-users@lists.xensource.com > >> Subject: Re: [Xen-users] xen kernel crashes athlon? > >> > >> Thanks for your reply.
